Success is when reality catches up to your imagination.

If we don't give things a try, nothing will get off the ground.

I only have one why, and my challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible.

My challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible. My why is to inspire people to do the things that inspire them so that together we can change our world. That's why I wake up every single day. I'm agnostic to the form it takes: I teach, I write, I speak, I advise.

I can't stand those people, speakers in a room, they say this all the time, "If I can just help one person in this room, I've done my job." You have an audience of 500 people and your standard of success is one person? That's terrible. If you help one person in the room, you're an abject failure. You have to change something.

Let us not attack those who disagree. Let us defend those who follow.

What's important to me is that I put messages out, whether it's a TED talk, whether it's a book.
